The year is 1930, and something is hunting infants and young couples in Economy Village, PA. When a local priest begins to suspect a demon may be the culprit, the sheriff calls in a team of Soldiers from the Sun. Caleb, Agni, Temple, and Li specialize in demon hunting, but they can't rule out an old religious sect as the true culprit. Prejudice, distraught parents, and angry townspeople don't make the team's job any easier. And if something goes wrong, they're on their own, because by the time their backup arrives, it will be too late.
